US Permissionless DollarPrice

(USPD)

USPD is a decentralized, permissionless, and natively yield-bearing stablecoin pegged to the USD. It aims to offer a stable, censorship-resistant digital dollar that is fully backed by on-chain collateral. Its design focuses on transparency and providing a yield-bearing alternative to other stablecoins by leveraging the Ethereum blockchain. It maintains its peg through a unique stabilizer mechanism and ETH collateralization, ensuring a verifiable, safe, and yield-bearing digital dollar without relying on traditional banking risks.

USPD achieves its price stability through a system of decentralized "Stabilizers." These Stabilizers are critical because they deploy their own funds to hedge against potential price volatility of the underlying Ethereum (ETH) collateral, effectively maintaining the dollar value of the collateral backing USPD. This mechanism, combined with the protocol's over-collateralization by staked Ethereum (stETH), ensures that USPD remains stably pegged to the US dollar in a decentralized and permissionless manner.

USPD is fully backed by on-chain staked Ethereum (stETH). This design provides complete transparency, as its reserves are 100% verifiable and auditable in real-time directly on the blockchain. Furthermore, USPD is natively yield-bearing. Holders automatically earn a sustainable yield because the underlying stETH collateral generates staking rewards from the Ethereum network, which are then passed directly to USPD holders, enhancing its value proposition as a stablecoin.

All DeFi protocols, including USPD, carry inherent smart contract risks, such as reentrancy attacks. While USPD's core audited code is robust, a significant exploit occurred in December 2025, resulting in approximately $1 million in losses. This incident, dubbed a "CPIMP" attack, targeted the deployment pipeline and compromised administrative keys, rather than a flaw in the audited smart contract code. This highlights the critical need for robust protocol design, ongoing due diligence, and secure deployment practices beyond just smart contract audits.

USPD distinguishes itself by being decentralized, censorship-resistant, and entirely independent of traditional banking system risks. It exclusively uses on-chain staked Ethereum (stETH) as collateral, offering complete transparency. In contrast, centralized stablecoins like USDT and USDC often rely on opaque, off-chain reserves or integrate heavily with traditional banking. While newer and potentially having lower initial liquidity than established stablecoins, USPD prioritizes native yield, transparency, and resistance to censorship over the conventional models.

USPD's decentralized nature provides significant benefits by offering greater user control over assets, enhanced privacy, and resilience against censorship. Unlike centralized alternatives, USPD is not controlled by a single entity, making it immune to freezing or seizure by external parties. This ensures unrestricted access to funds and protects users from potential attacks or interventions. Its foundational Web3 principles guarantee a transparent, secure, and user-controlled digital dollar experience, free from intermediaries and traditional financial system vulnerabilities.
